To assemble such a discharge tube, the second electrode 4 and the closed container 8 are heat-sealed using a sealing material 9 made of a brazing material or a glass material in an inert gas at normal pressure. After this assembly is completed, the unnecessary gas inside is evacuated from the through hole 2 of the pipe-shaped electrode 1, and then the active gas 7 is injected later, as in the first embodiment described above. While the filling gas 7 is being injected, the pipe-shaped electrode 1 is sealed by pressure at the external welding part 3.
